Abstract: Training neural network(s) (NN(s)) to solve optimization problem (OP) includes: configuring a first NN of the NN(s) with a first set of (FSO) values for NN parameters (NNPs); selecting a FSO training samples (TSs) for training the NN(s); providing the FSO TSs and a FSO first variables to the first NN to produce a FSO first output variables (OVs); evaluating an OP-performance-measuring objective function (OF) based on the FSO TSs and the FSO first OVs to provide a first value of (VO) a performance metric (FVOPM) of the NN(s); updating the NNPs based on the FVOPM; selecting a second set of (SSO) TSs for training the NN(s); providing the SSO TSs and the FSO first OVs to the first NN to produce a SSO first OVs; evaluating the OF based on the SSO TSs and the SSO first OVs to provide a second VO the PM of the NN(s); and updating the NNPs based on the second VO the PM.

Abstract: A mounting apparatus is provided for securing a fan. The fan has four corner portions projecting from two opposite sides thereof, the corner portions each define a mounting hole therethrough. The mounting apparatus includes a bracket for securing the fan therein, and two locking members. The two locking members each comprise a pivoting portion and a positioning portion spaced from the pivoting portion. The pivoting portion and the positioning portion respectively form a pivoting post and a positioning stub to respectively engage two of the mounting holes of one side of the fan, the fan and the two locking members are secured within the bracket.
